Capstone: Build, Ship and Operate the Product

10 Lektionen in dieser Stufe

1. Capstone Hardware Assembly and Bring-Up
   Build three units to the design and verify each against the bring-up plan. · Lab: Assemble the gateways, run the bring-up checklist and record measurements per serial number.
2. Capstone Data Acquisition Layer
   Read field and on-board sensors through the hardware abstraction layer with fault handling. · Lab: Implement polling of Modbus and I2C sensors with timeouts, retries and quality flags.
3. Local Storage, Buffering and Store-and-Forward
   Keep data through network outages and deliver it in order afterwards. · Lab: Buffer readings durably, unplug the network for an hour and verify nothing is lost or duplicated.
4. Capstone Local Web Interface and API
   Give installers a secure page for status, configuration and diagnostics. · Lab: Build a status and commissioning page with role-based login served over TLS.
5. Capstone Production Image: Read-Only, Signed and Reproducible
   Produce the release image through your pipeline. · Lab: Tag a release and let the pipeline build, test on the rig and sign the image and update bundle.
6. Enrolling the Pilot Fleet
   Provision the three units through the factory process and register them. · Lab: Run the end-of-line station for each unit and confirm identity, inventory entry and VPN reachability.
7. Rolling Out a Capstone OTA Release with a Canary
   Ship a real update safely and exercise rollback. · Lab: Release version 1.1 to one unit, promote it, then push a faulty 1.2 and confirm automatic rollback.
8. Fleet Dashboards and Alerts for the Capstone
   Operate the product from one screen with actionable alerts. · Lab: Build the fleet dashboard and alerts for offline, sensor fault, storage and update failure.
9. Acceptance Testing: Soak, Power-Cut and Network-Loss Runs
   Prove the requirements are met with recorded evidence. · Lab: Run a 72-hour soak, 500 power cuts and scripted network outages and file a test report.
10. Handover: Runbooks, Support Process and Maintenance Plan
    Make the product maintainable by someone who did not build it. · Lab: Write runbooks for the five likeliest incidents and a twelve-month maintenance and update calendar.

Abschlussprojekt

A finished product: three industrial monitoring gateways on a read-only, signed, A/B-updatable image, enrolled in your fleet, monitored and alerting, having passed soak, power-cut and network-loss tests, with runbooks for whoever maintains them.
